Fletcher,

With 0.15.0, there was a significant reorganization of the input code to
better support handling of mbox files and maildir and MH directories. 
Since the "From " line is added locally to a message, its fields
duplicate other header fields.  Thus, scoring its tokens is a
duplication.

What you've noticed is an intentional change in behavior.
